Abstract

Hirschmanniella kaverii sp. n. collected on rice roots froom Kaveripattinam, Tamil Nadu, India, is illustrated and described. It can be distinguished from H. oxycrena Sultana, 1978 and H. mangalorensis Mathur & Prasad, 1971, by the presence of five distinct lip annules, pointed central extension of tail and the absence of mucro at tail terminus. It differs from H. exigua Khan, 1972, by the longer stylet (24–25 μm vs. 17–18 μm) and larger anteriorly sloping stylet knobs and absence of mucro in tail). It can be distinguished from H. shamimi Ahmad, 1972, by the absence of ventral notch near tail terminus.
